  • Publication number: 20240108505
    Abstract: An ophthalmic surgical irrigation assembly for attachment to an ophthalmic surgical instrument. The assembly includes an elongated sleeve having a hollow interior space through which fluid is passed and surrounds a majority length of a cannula attached to the ophthalmic surgical instrument. A fluid port formed adjacent a distal end of the elongated sleeve allows the fluid to exit the interior space. A distal opening in the elongated sleeve allows a distal portion of the cannula to extend beyond the distal opening. A hub integrally formed with a proximal end of the elongated sleeve is adapted for fluid tight attachment to at least a portion of the surgical instrument and allows fluid to flow from the surgical instrument through the interior space and exit out of the fluid port. The elongated sleeve and the hub are each formed of a polyether block amide resin.

  • Publication number: 20230248541
    Abstract: A method for preparing a femur for receiving a prosthesis. The method includes the following: fixing a femoral trial component to the femur; coupling a reamer bushing relative to the femoral trial component; reaming a cavity into the femur using the reamer bushing as a guide; coupling at least one of a modular femoral box trial and a stem adapter relative to the femoral trial component; trialing the femoral trial component with the articulating surface of the femoral trial component; and performing the coupling of the reamer bushing, the reaming of the cavity, the coupling of the at least one of the modular femoral box trial and stem adapter, and the trialing of the femoral trial component all while the femoral trial component remains fixed to the distal femur.

  • Patent number: 9161761
    Abstract: An instrument set and related method for preparing a proximal tibia during a bi-cruciate retaining procedure are disclosed. The instrument set can include a tibial resection block, a cut guide, and a locking arm. The tibial resection block can be configured to be fixed to an anterior portion of the proximal tibia. The tibial resection block can define a slot that extends in a medial-lateral direction when the tibial resection block is fixed to the proximal tibia. The cut guide can have a body, a medial arm, and a lateral arm. A medial cut slot can be defined between the body and the medial arm. A lateral cut slot can be defined between the body and the lateral arm. The cut guide can further comprise a tongue extending therefrom. The tongue can be configured to be received by and slidably translate along the slot of the tibial resection block.

  • Patent number: 9155615
    Abstract: An intraocular lens (“IOL”) cartridge includes an upper wall and a lower wall, together defining a lumen for receiving an IOL. The proximal end of the cartridge has an open slot cut into and through the entire thickness of the upper wall so to allow the leading haptic of the IOL to extend above the upper wall. The cartridge includes a proximal-end feature to facilitate folding of the leading haptic radially inward relative to the optic as the IOL moves into the lumen.

  • Patent number: 8979847
    Abstract: A method for preparing a femur for receiving a prosthesis can include positioning an intramedullary (IM) member in the femur. A femoral trial component can be positioned onto a distal end of the femur. The femoral trial component can have an attachment portion and at least two cut surfaces thereon. A modular boss assembly can be attached to the attachment portion of the femoral trial component. The modular boss assembly can have a boss stem that is configured to operably connect to the IM member. A desired contact between the femoral trial component and the distal femur can be confirmed based on the attaching. The femoral trial component can be fixed to the distal femur based on the confirming. The modular boss assembly can be removed from the femoral trial component. A reamer bushing can be coupled relative to the femoral trial component.

  • Publication number: 20140135782
    Abstract: An IOL injector cartridge, comprising an upper wall, a lower wall, the upper wall and the lower wall combining to define a lumen that extends from a proximal end to a distal end, a slot extending through the entire thickness of the upper wall and extending from the proximal end and having a slot distal end formed by the upper wall, an edge of the upper wall that, at least partially defines the slot, having a convex curvature, the curvature occurring along the thickness of the edge.
